教师每天要上课,上课就要讲话,讲话就要用嗓子(喉)。如何保养嗓子,使我们在噪上发音适当,学生听来第一排不振耳,最后一排听得清,并且抑扬顿挫,运用自如,我认为: (一)发音方法要讲究——发音的音量是由呼吸的强度来决定的。呼吸有胸呼吸和腹呼吸两种,这两种呼吸要交替使用,音调才能抑扬顿挫。教师在强调教材重点需要适当提高音调的时候,要以腹式呼吸为基础,结合使用胸式呼吸,千万不可尽量使用胸式呼吸,以致损伤声带而造成声音嘶哑。(二)控制吐气量要自然——上课时除注意音调要根据教材的需要外,还要采取“讲写结合”和“启发思维,师生对讲”的方法来控制和调节声带的活动。控制吐气量要自然,恰 The teacher wants to have a class every day, class must talk, speech must use the throat (throat).

(B) to control the amount of breathing to be natural - in addition to pay attention to tone in class according to the needs of teaching materials, but also to take “combination of speaking and writing” and “inspire thinking, teachers and students intercom” approach to control and regulate vocal activity. Control of expiratory volume to be natural, just
